Application filed. December 28, 1910. Serial No. 599,774.

To all whom it may concern:

Be it known that 1, JOHN LINCOLN GISH, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented a new and useful Regulated Automatic-ClosingValve, of which the following is a specification.

The object of my present invention is to construct a regulated automaticclosing valve, in such a manner, firstly, that the water in the tankwill be retained under direct pressure, until the said water is requiredfor flushing; secondly, thatthe water in the tank will be discharged ina large volume, under direct pressure, into and through thevalve-casing; thirdly, that the flushing stream, after passing theoutlet in the valve-casing, performs no other work or function, but thatof flushing; and fourthly, after the flushing has been completed, forthe regulated automatic closing valve, to be closedautomatically, theapparatus be ready, to repeat its work, as hereinafter described.

Figure 1, is a perspective of my improved apparatus. Fig. 2, is avertical section thereof, with the valves 1)., and K., in the closedposition. Fig. 3, is a vertical section thereof, with the valve 1).,open, and the valve K., closed. Fig. i, is a vertical section thereof,with the valves 1);, and K., in the open position. Fig. 5, is a verticalsection thereof, with the valveD., closed, and the valve K., open. Fig.6, shows the regulating plate R, adjusted to a different position, inorder to regulate a shorter flushing stream.

In the drawings, self closing valves, of the reciprocating type areshown.

Like letters of reference, refer to like parts, in the severalfigures.

In Fig. 1,E., is the tank, fastened fluidtight, to the removablevalve-casing T. 1., is the inlet, to the tank 1). T., is thevalvecasing. P., is a face plate, fastened fluidtight, to thevalve-casing T. R, is a regulating plate; 0., is a stop pin, in theregulating plate R; 8., is a slot in the regulating-plate R; 88., is aset screw, which fastens the regulating plate R, to the face plate P.H., is a handle; 0., is a counterbalance, to handle H. to an operatingspindle, which passes through the face plate P. 0., is the outlet to thevalve-casing T. The usual connec- (L, is a set nut, joining the handleH,

tions with the service pipe, and the discharge pipe, are made at 1., and0., respectively. A., is a supporting arm,'projecting from the inside ofthe valve-casing T., and engaging the spindle S. S., is an operatingspindle, which passes through the face plate P, (Fig. 1,) at a. 13., isa finger, firmly fixed, upon the spindle S. (L, is a valve stem, to thevalve D. 1)., is the relief valve, to the valve K. (Z., is the valveseat, to the valve 1)., in the-valve K. 22., is the conduit, from (Z.,through the valve K., at some point removed, from the central aXis ofthe valve K. m., is an adjustable weight, attached to the valve stem (L,by the set pin L K., is the main valve; K., is its flat valve seat, inthe valve casing T. T., is a removable casing, which incloses the mainvalve K., and forms a part of the valve casing T. O'., is an inlet, tothe casing T., from the tank E. X., is a chamber, in the casing T.,above the valves 1)., and K.

The special features of my device are described as follows :The mainvalve K., is a heavy weighted valve (not buoyant) which slides up anddown in the valvecasing T., in such a manner, so that it is only, by orwith great pressure, that air or water, can be forced or filtered,between the outer wall of the valve K., and the inner wall of the casingT. The said valve K., has a con cave bottom, so as to form an annularring, on the bottom of the said valve K.; and the said annular ringcontacts the flat valveseat K.

The weighted vent-valve 1)., is recessed, in the top of the valve K.,and its solid stem (L, projects through the main valve K. The solid stem(L, is so constructed, that it slides, so snugly, up and down, in. itspassage way, through the valve K., that when the ventvalve 1)., isopened, no air or water, escapes along the line, of the valve-stem (LHence, by such a construction, with no lateral motion, to the solid stem(L, the valve 1)., with its recessed valve-seat (L., is assured of apositive seating, upon its valve-seat (Z, p ro viding the adjustableweight m., is attached to the valve-stem (L, by the set pin L, as willbe explained below.

it-h such close coadaptation of surfaces, of the valve 1)., and itssolid valve-stem (L, with the valve K., and yet give completeventilation to the valve 1)., when opened, it

is necessary to provide a conduit, through the valve ii, at some pointremoved from the central axis of the valve ii; which said conduit willbegin at the lower edge of the valve-seat (.Z., and open or end, in thebottom of the valve hi; as for example, the conduit its to theadjustable weight 171., which is attached to the valve-stem (Z, by theset pin 2 the said weight 772., performs special work, besides acting asa stop, to limit the distance, the valve 1)., is raised from its'alve-seat (Z., or to act as a part of the means, which raises the valveK., after the valve 1)., has been opened namely, the said weight 772 isthe force or means, which draws quickly, the valve-stein (L, back to itsstarting position, thereby assuring a quick and positive reseating ofthe valve 1)., after the means, for opening the valve 1)., has brokencontact, with the valve-stem cl, and also, after the valve 1)., has beenrescated, by the action of the weight 1a., the said weight 122., holdsthe vent-valve 1)., upon its valvcseat (Z., as the main valve 121.,descends to its valve-seat K., thereby otl'ering a great resistance tothe air, which is trying to reenter the chamber X., through the conduitand the valve-scat (Z., as the main valve 1a., descends to itsvalve-seat K.

In the act of the opening of the valves 1)., and K., we displace throughthe conduit .22., the air and water, that may have been confined withinthe chamber X. New, by a prearranged relation of parts, we allow thevalve 1)., to close, and leave the valve K, suspended within the casingl see Fig. 5. This suspended relation, of the heavy weighted alve 1i,Fig. 5., is in proportion, to the assembling of the parts, 'lC., K.,1)., (L, and my whereby we govern, the balancing of the force ofgravity, which acts upon the valves, and the pressure beneath saidvalves. And this is accomplished, by hav ing the device so constructed,and the parts so assembled, that it is only, by or with greatpressure,that air or water, can be forced or filtered, into the chamber X,between the outer wall of the 'a-lve IQ, and the inner wall of thecasing T., and since air, cannot easily or quickly, reenter the chamberX, by way of the conduit and the valveseat (Z., by reason of the fact,that the valve 1)., is held down, upon its valve-seat (Z., by the weight7a., which is attached to the valvcstem (2., it is readily seen, that wehave gradual control, over the air, which is try ing to reenter thechamber thereby giving us a gradual, regulated, self closing of thevalve H. You will notice that I say, control over the air, which istrying to re enter the chamber X. The reason for this statement is,-thatwhen the valve K, be gins to close, the tank 1*), is practically emptyof water, and the valve IQ, being so far removed from its valve-seat KC,there is nothing but air, to find its way, into the chamber X. And alsoby way of reference, would say, that the device is so formed, that thecontents of the tank ll, is expelled, at some little time, before thevalve K., is closed, thereby allowing for an extra amountof water, totlow from the inlet 1., into the tank E, and to pass directly, to andthrough the valve-seat KC, and thus serve, as the quantity of waterneeded, to refill the closet bowl, after the closet bowl. has beenflushed, and before the valve K, is closed.

The means, employed to open the valves l), and K, becomes a feature,-notin the way the valves 1)., and K, are opened; but as soon as the valves1)., and K., are opened, the said means, by releasing the operatinghandle H, breaks contact, see Fig. 5., with the said valves, and allowsthe immediate closure, of the valve l)., by means of the weight 9a.;thus performing a specific act or function, in leaving the valve 1i,suspended in the casing T., see Fig. 5., for a predetermined time. inorder to regulate, the self closing of the valve K.

liith the special features thus described, my device, performs its workas follows: ln Fig. the valves 1)., and ii, are in the closed position.ater is allowed to enter the tank lth, through the inlet 1. into thesaid tank Pl, water will 'tlow, until the air, within the tank it, hasbeen compressed, to

an equal degree, with the water pressure,--

from the service pipe. As the tank E, is tilled. with water andcompressing the air therein, as soon as the air and water pressure,within the tank 1 has become. of a sutlicient pressure, to overcome, theresistance, that is offered, to either air or water, by the closeceadaptation of the outer wall of the valve hi, and the inner wall ofthe casing T., then and not befor water passing through 0, will beforced between the two said surfaces, of the valve IQ, and easing T.;and. this forced filtration, between the outer wall of the valve l l,and the inner wall of the casing T., will be continued, until the airwithin the chamber 21., will be of the same compression, as the airwithin the tank This compression of air and water, within the chamber31., will force the valve hi, downward, upon its valves+at K., andassin'e a positive closure, of said valve K.

in Fig. 3., the operating means, ll, 8., and P, are shown, as havingopened the valve and thereby relieved. the chamber 31., from itspressure of confined air and water; said air and water having beendischarged, tl'irough the valve-seat (Z., and the conduit 22., downward,through the valvc seat K. The quantity of water, that has been confined,within the chamber FL, is so small, that it is not considered of aflushing nature. Now, with the pressure removed from the chamber X., bythe opening of the valve 1)., a full downward motion of the handle 11.,will operate the means, 11., S., 1%., (Z, and 7a., which will easilypush the main valve K., upward into the chamber X., and away from thevalve-seat K., Fig. 4e, and allow the contents, of the tank E., to passinto the opening O., and directly through the valve-seat K., into thedischarge or flushing pipe, at 0.; and in the act of discharging,thewater in the tank 13., is forced into the flushing pipe, under the heavycompression of air, aforesaid, that has been confined within the tank E.

As soon as the valve K., Fig. 5., has been pushed up into the casing T.,and the handle 11., is released, the counter-balance 0., returns thehandle 11., which rotates the spindle S., to which is firmly fixed thefinger 13., back to their starting position; thereby breaking contact,with the valvestem cZ-., which act, allows the immediate closure of thevalve 1)., by means of the weight 77%., which is attached to thevalvestem (L, and leaves the valve K., suspended within the casing T'.,as shown in Fig. 5.; and as stated above, the valve K., Fig. 5., willdescend slower or faster, in proportion, to the assembling of the,parts, T., K., D., (Z., and m., and thereby return the parts, to theirrespective positions, as shown in Fig. 2., and leaves the device ready,to repeat its work.

The regulating means R, 8., 88., and 37., performs its work as follows:-1n Fig. 6., the dotted lines, show position of the regulating plate R,adjusted so that the handle 11., can make a full downward motion andopen the valve K., to its fullest extent, for a full flushing stream,before the handle 11., comes in contact, with the stop pin 37. Now inorder to make a shorter flushing stream, the regulating plate 1%., isadjusted as shown in Fig. 6., bringing the stop pin 29., closer to thestarting position of the handle 11., thereby limiting the downwardmotion, of the handle 11.; and the shorter we make the downward motionof the handle 11., by the re-adjusting of the plate R, the shorter willbe the opening of the valve K., and the shorter, the opening of thevalveK., the shorter the flushing stream, will be.

From the above description, it will be noticed, that the first, second,third, and fourth objects, of my present invention, as above mentioned,are fully accomplished.
